LONGITUDI'NAL FIBROUS PACKING FOR PLUNGER PUMPS.

Application filed July 28, 1924, Serial No. 728,653.. Renewed October 3, 1927.

embodiment of apparatus of my'inventionv shown in the accompanying drawing; it being understood that other modifications7 variations and adaptations ymay be resortedk to within the spirit of the invention and the scope thereof as here claimed.

The invention consists of apparatus achieving the objects. Y

Fig. l is a longitudinal section of the puinp.k

Fig. 2is a top end view of a packing unit.

Fig. 3 is a longitudinal section of a packing unit. p i

Fig. @is an end view of apacking ferrule Fig. 5 is an elevation of the ferrule.

Screwed onto the llower end of the packing barrel B2 is a collar Cin which is screwed a' bottom barrel B3 which has on its bottom end a coupling D having a ring seat 7 for a packing ring 8. A gland 9 screws into coupling l) and receives the upper end of a standingvalve barrel B* which has a shoe S from which depends the anchor or suction pipe A.

Normally standing in and on the shoe S is any suitable type of standing valve instru-` mentality V, here shown as of three story type, that is, having three valves 10. The standing valve sleeve 1I is embraced by the packing 8 and this stops sand from settling down around the stucture V and keeps it free so that it'can be readily lifted out.

Included in the stationay elements of this pump is the plunger packing, one unit of which is shown in detail in Figs. 2-3. Each unit includes a base ring R peripherally recessed at 14 and rough faced so as to bite into applied ends of hanks or plaits 12 of fiber strands forming the packing P. To clinch the bottom or butt end of the packing in base ing to press it to its seat in recess 14. Preferably the upper ends of the plaits or hanks of fiber packing are ravelled outto form a brush-like endP creating a mat for sediment to pack iii and provide a dense packing body. Any number of packing uni-ts is strung along the packing rbarrel B2 and each has a spacing jacket J to prevent the base rings .R from shifting iii the barrel. A set of units is held between couplings, as C.

A distinctive feature of this pumpl is that 'lie packing barrel (B2) is packed for its fullA consisting oflongitudinally lying fibrous strands forming a cylinder in whichthe plunger slidingly works, and spacing ackets holding each unit against longitudinal move-V ment along the barrel.

2. In a plunger pump, a barrel, and an upstanding, fibrous packing cylinder having longitudinal strands and presenting an internal bearing surface, held4 stationary in the barrel and in which the pump plunger wor is.

` I iraniani` ring R a ferrule l5 is jambed on the packi 3. In a plunger pump, a' packing device.

consisting of a cylinder of longitudinally lying strands ravelled out-at one end to forni a mat or brush to collect sediment.

' si. LA plunger. pumppacking device com- Y l .prising an outer sleeve-like jacket, a base plunger and barrel means, an elongated sleeve of fibrous packing having longitudinally veX- tending strands, and means for preventing end movement of the packing.
